Jack Applin (one of several people to send this to me): I get the implication of “You’re in the marines? The army must have rejected you,” but the significance of the parking lot escapes me. Are Dr. Shipley’s marine skills doubled in parking lots, so he can easily kill Leo for this offense?

Chris Reaves: Okay, this Doonesbury went over my head. Is the idea that the birthers won’t believe even the actual physical document? That they won’t show up to see it? That displaying it would be giving in to terrorists? That the birth certificate in fact DOES say “Kenya” on it? None are really funny. Furthermore, the language itself seems to imply that it’s the last option (the sentence trailing off where it does suggests the problem is with what they would see) which would be an incredibly uncharacteristic joke for Trudeau.
